AUTOMATIC SLIDING SHELF FOR COOK-STOVES.

SPECIFICATION forming part of Letters Patent No. 355,180, datedDecember 28, 1886.

Application filed September 14, 1885. Serial No. 177.080.

To allgwwm, it may concern:

Be it known that I, Mnfr'riinw KUEHNLE, of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Automatic Sliding Shelves for Cook-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a perspective view of a stove embodying my invention, showing one of the doors open and the shelf pulled out. Fig. 2 is a horizontal section of the stove just above the shelf, showing the doors closed.V

My invention relates to certain improvements in automatic sliding shelves for cool;- stoves; and my invention consists in features of novelty, hereinafter fully described, and

pointed out in the claims.

Referring to the drawings, similar letters of reference illustrate likeparts in both the iigures.

My invention as an attachment to cookstoves presents an easy automatic means of withdrawing the oven -shelf simultaneously and in conjunction with the opening of the door forthe inspection of the roast, &c.

A represents an ordinary cook-stove, and B one of the oven-doors to the same.

O is an arm or lever secured to a projection, B', on the door, or attached to the door in any other suitable way. This arm has a teat or lug, C', that works in a slotted way, D', of the sliding shelf D. Y

It will be seen that as the door B opens, the lug C on the end of the arm moves freely in the groove until it reaches the `sharp curve near the edge of the shelf. It then follows la course parallel thereto, so that the door opens at first free of any action on the shelf sufficiently for inspection, and when it operates the shelf the course of the slot is s'o nearly that of the lug that engages in it, so that it is operated very steadily-an object of considerable importance-'vas the contents of the pans are frequently of a liquid nature; and in other cases-as with bread, cakes, and biscuit-any'jar is apt to make them sad and heavy.

' D2 are ridges or runners beneath the shelf on which it slides on the bottom of the oven, although I do not confine myself to that means (No model.)

of supporting the shelf, foriit is evident it may run on the usual ledges or side brackets provided in the ovens of cook-stoves, and may also be thus used for upper shelves as well as lower ones without departing from the essential features of my invention.

D3 are projections or stop-pins on the sliding shelf, which, when it has reached the intended eXtent of its withdrawal, come in contact with projections or lugs Dt, that stop its further progress. These projections, which overlap the shelf, also steady its motion as it slides, and when it has 'reached its limit of withdrawal prevent its tilting. When the shelf is made to slide on the usual supportingledges, similar' projections are used to steady its movement, stop its entire withdrawal, and prevent its tilting.

It will be seen that the gradual curved way K in which the pin of the withdrawing-arm works operates on the shelf without any danger of disturbing the contents of the dishes resting on the same.

My automatic shelf is easily attached to any ordinary cooking-stove.

I claim as my inventionl. The combination, with a stove, the door having an arm projecting therefrom, and a lu g on said arm, of a sliding shelf having a slot, said slot being parallel with the outer edge of the shelf for a short distance and then curved outwardly toward the side of the shelf, substantially as and for the purpose set forth.

2. The combination, withv a stove, the door having an arm projectingtherefrom, and a lug on said arm, of va sliding shelf having a slot curved outwardly from the outer edge of said shelf and parallel therewith for a sufficient distance, and in which the lug of said arm works, runners on the shelf', stop-pins, and overlapping lugs against which said stop-pins inipinge and prevent the withdrawal of the shelf, substantially as and for the purpose set forth. 3. The combination, with a stove, the door having an arm projecting therefrom,andalug on said arm, of a sliding shelf having a slot, a portion of which is parallel with the outer edge of the shelf, substantially as and furthe' purpose set forth.
